commiteb8500b874upstream. After commit81ad4276b5("Thermal: Ignore invalid trip points") all user_space governor notifications via RW trip point is broken in intel thermal drivers. This commits marks trip_points with value of 0 during call to thermal_zone_device_register() as invalid. RW trip points can be 0 as user space will set the correct trip temperature later. During driver init, x86_package_temp and all int340x drivers sets RW trip temperature as 0. This results in all these trips marked as invalid by the thermal core. To fix this initialize RW trips to THERMAL_TEMP_INVALID instead of 0.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
